FLUSHING-VALVE.

Application filed January 8, 1917.

To all whom z'zf may concern.'

Be it known that I, JOSEPH HUsA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventedV certain new and useful Improvements in Flushing-Valves, 0f which the following is a specification.

The present invention has to do with improvements in flushing valves, such as are used in connection with toilet fixtures and the like. The invention has particular reference to a construction of this type of 1valve, such that the operation of the valve may be commenced by tripping. a trigger or the like, after which the flushing operation will continue automatically for a predetermined length of time. i

Certain objects of the invention are to provide a valve of simple mechanical structure and one which can be cheaply and easily manufactured from a small number of parts easily assembled. Another object is to simplify the construction and operation of the device, so that it will not easily be thrown out of adjustment or repair, but will continue to function properly with a very small amount of attention.

Another object is to provide what I shall term an oil-cased valve-that is, one in which most of the operating parts are iooded with oil at all times, so that they will at all times be properly lubricated and protected against rusting and the like.

Other objects and uses of the invention will appear from a detailed description of the same, which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referring to the drawing:

Figure 1 shows a vertical cross-section through the assembled valve, the parts standing in their normal or closed position;

Fig. 2 shows a horizontal section taken on line 2-2 of Fig. l, looking in the direction of the arrows;

Fig. 3 shows a horizontal section taken on the line 3 3 of Fig. 1, looking in the direction of the arrows; and

Fig. 4 shows a fragmentary. horizontal section Vtaken on the line l---fl of Fig. 1 looking in the direction of the arrows.

Referring now to the construction shown in the drawings, the same comprises upper and lower chambered members 5 and 6. The member 6 lis provided with an upper circular casing 7 having a plurality of openings 8 Specification of Letters Patent.

through which the water is discharged to the fixture. The lower portion of the member 6 is provided with a waterconnection 9 by means of which the water is delivered into the flushing valve. An annular flange 10 encircles the central portion of the member 6. The chambered member 5 has a downwardly depending circular flange 11 which seats within the circular casing 7, but provides an annular space in conjunction therewith. In the lower portion of the circular flange 11 there is a plurality of openings 12 by means of which the water is delivered into said annular space, so that the water may thereafter find its way through the openings 8.

The lupper chambered member 5 has its lower portion 13 threaded into the upper portion 14 of the lower chambered member 6. Then the parts are threaded together,

the lower edge of the circular flange l1 is pressed toward theannular flange l0. A circular flanged plate 15 is clamped between the lower edge of the circular flange 11 and the annular flange 10, anda gasket 16 may be interposed between these parts for the purpose of insuring a water-tight Vconnection. The inner periphery of the circular plate 15 constitutes a valve seat for the main 4or secondary valve.

Within the chambered member 5 is an oil chamber 17, and a plunger 1S works within said chamber. Said plunger comprises a pair of plates threaded onto the rod 19 and clamping between them the cup washer 20. This cup washer faces upwardly, so that the plunger can be readily depressed, and when so depressed will allow the oil to readily flow into the upper portion of the chamber,

but so that on the upstroke of the plunger,

the oil will be prevented from leaking past the cup washer. The rod 19 extends down through the lower end of the upper chambered member 5, passing through a stuffing box 21. A helical spring 22 works within the upper chambered member and tends to raise the plunger 18 and the rod 19. Within the circular flange 11 there works a plunger 23. This plunger is mounted on the upper portion of a circular member 24C surrounding the rod 19, but spaced therefrom so as to provide an annular passage way 25. The lower portion of the circular member 24 carries a circular flange 26 which constitutes a valve and is adapted to seat against the lower face of the circular plate 15. An-

lll@

other circular member 27 is threaded onto the lower end of the member 24. VThis circular member 27 has an upstanding iianged seat 28 which is also adapted to seat against the lower surface of the plate 15. The circular member 27 also has a downwardly de pending circular valve seat 29 for the primary valve. On the lower end of the rod 19 is the valve member 30 which, when the rod is raised, contacts against the lower periphery of the circular valve seat 29, so aS to close the opening thereof.

The valve member 30 is provided with a peripheral flange and within such flange there is provided a compressible washer or the like, which is adapted to seat firmly against the lower edge of the circular valve seat 29.

The upper portion of the upper chambered member 5 is provided with a removable cap 31, by which the interior of said member may be rendered accessible. An oil passageway 32 establishes communication between the upper and lower faces of the plunger 18, and a needle valve 33y serves as a convenient means for controlling the flow of oil through said passageway, and thus serves to regulate the speed at which the plunger will rise through the upper chambered member 5.

The operation of this device is as follows: Upon depressing the plunger 18, the

rod 19 will be lowered and the helical spring 22 will be compressed. The lowering of the rod 19 will carry with it the valve member 30, so that the circular valve seat 29 will be uncovered, and water will be allowed to flow up through the passageway 25 and against the upper surface of the plunger 23. Said plunger will thereby be lowered, thus lowering the flanged valve 28 and the circular ange 26 away from the circular plate 15. This will uncover the secondary valve, so that the fiushing water will be allowed to flow directly through the opene ings 12 and 8 to the fixture. The lowering of the circular member 24 and the plunger' 23 will be limited by the contact of the circular valve seat 29 against the valve member 30, so that the extent of said lowering will be dependent upon the amount which the plunger 18 and rod 19 were originally lowered.

As soon as pressure on the plunger 18 is released, the helical spring 22 will commence to raise said plunger and the rod 19, and thus the flanged valve seat 28 and circular flange 26 will gradually rise until they contact the circular plate 15, at which time the secondary opening will be closed.

I will now explain the manner in which the lowering of the plunger 18 and associated parts may be effected. Alongside of the main oil chamber 17 is an auxiliary chamber 34 within which works a vertically movable pin 35. This pin operates through a stufhng box 36 in the upper end of the chamber 34. The lower end of the pin 35 is enlarged, and a spring 37 presses upwardly on said lower end, `so as tonormally raise the pin into elevated position shown in Fig. 1.

An opening 38 provides communication between chambers 34 and 17. A lever 39 is pivoted at the point 40 within said opening 38. The longer arm of said lever is bifurcated as at 41 in Fig. 2, so as to straddle the upper' end of the rod 19. A Vroller 42 works between the bifurcations 41 and contacts the upper surface of the plunger 18. The inner Vend or short arm of the lever 39 carries a finger 43. An annular collar 44 encircles the pin 35, the lower Ysurface of said collar being beveled and its upper surface being abrupt, as is well illustrated in Fig. 1. UponV depressing the pin 35 the lever 39 will be Y tilted upwardly, while the collar 44 passes beneath the finger`43. As long as the pin 35 is maintained in depressed position, the spring 37 will remain compressed and the collar 44 will occupy its position beneath the pin 43. Upon releasing the pin 35, as by releasing pressure on the seat, the spring 37 will be allowed to raise the pin 35 provided said spring be of sufficient strength. By making the spring 37 of sufficient strength, it will force the pin 35 upwardly, rocking the lever 39, and lowering the plunger 18 and compressing the helical spring 22. The plunger 18 will be lowered the extreme distance because the rising of the pin will, of necessity, tilt the lever 39 a sufficient distance each time to permit the collar 44V to come past the finger V43.

As soon as the pin 35 has risen Va sufficient distance to permit the finger 43 to slip over the collar 44, the plunger 18 will commence to rise under the influence of the helical spring 22 and the rate of rise and the period of time so occupied, which will be the flushing period, will be regulated by the amount of opening of the needle valve 33. Y

I desire to point out the fact that the construction herein disclosed is very well adapted for use in direct conjunction with a bowl, and, when so used, the pin 35 may be directly contacted by the lower surface of Vthe seat.
